17 Jan 1946 Clarence E. McClung	science	death Clarence E. McClung Died 17 Jan 1946 at age 75 (born 5 Apr 1870). Clarence Erwin McClung was an American geneticist and paleontologist who discovered the role of chromosomes in sex determination in a species of grasshopper. In a key paper, he reported that sperm exist in two forms, each with a different chromosome configuration. Thus, he was one of the first (1901) to deduce that chromosomes determine the sex of offspring. McClung also studied how the behaviour of chromosomes in the sex cells of different organisms affects their heredity. His theory was one of many that inspired scientists to pursue investigations such as the Human Genome Project, an attempt to map the structure and location of all human genes. He also published on Cretaceous fishes.

18 Jul 1946 Charles Hubbard Judd	science	death Charles Hubbard Judd Died 18 Jul 1946 at age 73 (born 20 Feb 1873). American psychologist who was a leader adopting the scientific method in the study and reform of education. His own research included the nature and development in reading, language, number ideas and their development, writing, and the higher mental processes. He examined the psychological issues of school curriculum and the pedagogical methods used in education. He believed an overarching educational objective was to developing the learner's social consciousness, rather than the expression of an individual's instinct, but to participate in a cooperative social experience. He filed an affidavit at the Scope's trial in strong support of the teaching of evolution in schools.

14 Oct 1946 J. Craig Venter	science	birth J. Craig Venter Born 14 Oct 1946. American molecular geneticist who pioneered the use of automated gene sequencers. In 1990, he developed "expressed sequence tags" (ESTs), a new strategy for gene discovery and tagging that revolutionized the biological sciences. In 1995, Venter, in collaboration with Hamilton Smith, determined the DNA sequence of the entire genome (all the genetic material of an organism) of Hemophilus influenzae, a bacterium that causes earaches and meningitis in humans. The achievement marked the first time that the complete sequence of a free-living organism had been deciphered, and it was accomplished in less than a year. He founded the Institute for Genomic Research (TIGR). By 2000, his company Celera Genomics sequenced the human genome.

13 Nov 1946 Artificial snow	science	Artificial snow In 1946, artificial snow from a natural cloud was produced over Mount Greylock, Mass., for the first time in the U.S. An airplane spread small pellets of dry-ice (frozen carbon dioxide) for three miles at a height of 14,000 ft. Although the snow fell an estimated 3,000 feet, it evaporated as it fell through dry air, and never reached the ground. The experiment was carried out by Vincent J. Schaefer of the General Electric Company. Earlier the same year, he had produced snow in a cold chamber, on 12 Jul 1946.
08 Dec 1946 Snow-melting apparatus	science	Snow-melting apparatus In 1946, the first test in the U.S. of a snow-melting apparatus embedded in a sidewalk was made in New York City. The department store, Best & Co. installed 15 coils made up from 4,530 feet of pipe. A mixture of about 67% water with 33% Zerex was circulated, effective to prevent freezing to as low as -5 deg.F. It was first put to use shortly thereafter, on 26 Dec 1946, during a blizzard. This was not the first method to melt snow devised in the U.S. On 27 May 1890, black American inventor F.J. Farrell was issued a patent for an "Apparatus for melting snow" (No. 428,670), which was a cast-iron box laid beneath the street gutter and heated with steam.
11 Dec 1946 patent	science	patent (computer science) Frederick Williams receives a patent for a random-access memory device.
